CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 15/593,718, filed May 12, 2017, and claims priority to Chinese Application Serial No. 201610316878.5, filed May 12, 2016, the disclosures of which are hereby expressly incorporated by reference herein in their entireties.

FIELD OF THE DISCLOSURE

The present disclosure relates to a valve for use with an inflatable product. More particularly, the present disclosure relates to a combined inflation and decompression valve for use with an inflatable product, and to a method for using the same.

BACKGROUND OF THE DISCLOSURE

Traditional air valve assemblies of the type for use with inflatable products (such as mattresses, chairs, pools, spas, floats, etc.) include fill valve components. However, such conventional air valve assemblies typically do not provide for an automatic decompressing function, such that when the product is over inflated, air in the air chamber cannot exhaust out. As a result, if the internal portion of the product is in an over inflated state (i.e., has an internal pressure greater than a decompression value), and if the product is pressed by sufficient external force, it may burst or explode.

Prior attempts to combine an air valve and a decompression valve, have resulted in a simple decompression function as the internal portion of the product is over inflated. However, when the decompression valve is open to deflate, it does not automatically close in response to a reduction of air pressure. Additionally, the internal components of the decompression valve may shake or rattle as a result of air flowing when open, and thus may tend to break.

SUMMARY OF THE DISCLOSURE

The present disclosure provides a valve assembly configured for use with an inflatable product, such as a mattress, chair, pool, spa, float, or another suitable inflatable product. The valve assembly includes a first valve component that serves as an air inlet for inflation of inflatable product, and a second valve component that serves as an air outlet for deflation or decompression of inflatable product.

According to an embodiment of the present disclosure, an air valve assembly includes an air valve component and a decompression valve component. The air valve component includes an outer body defining an internal receiving chamber, and an air valve in fluid communication with the internal receiving chamber, the outer body including an air hole fluidly connecting the internal receiving chamber and an air chamber of an inflatable product. The decompression valve component is received within the internal receiving chamber and supported for longitudinal movement within the internal receiving chamber between a sealed state and an open state. The decompression valve component seals the air valve of the air valve component from the air hole of the outer body in the sealed state. The decompression valve component fluidly connects the air valve of the air valve component and the air hole of the outer body in the open state. The decompression valve component includes a decompression passage fluidly connecting the air chamber and atmosphere. A sealing portion is configured to close the decompression passage in the sealed state, and a limit portion is operably coupled with the sealing portion. When air pressure within the internal receiving chamber is greater than a decompression value, the sealing portion and the limit portion move relative to each other, and the sealing portion abuts the limit portion to move the decompression valve component from the sealed state to the open state.

According to another embodiment of the present disclosure, an air valve assembly includes an outer body defining an internal receiving chamber and having a plurality of air holes fluidly coupling the internal receiving chamber and an air chamber of an inflatable product. An air outlet is supported by the body and is configured to provide selective communication between the air chamber and atmosphere. An air valve device is supported by the outer body and fluidly coupled to the air chamber through the air holes of the outer body and the internal receiving chamber. The air valve device includes a valve rod and a seal supported by the valve rod, the valve rod being movable between a sealed state and an open state. The seal cooperates with the outer body to block air flow in the sealed state, and the seal is in spaced relation to the outer body to define a passageway between the seal and the outer body in the open state. The valve rod is biased toward the sealed state. A decompression valve device is supported by the outer body and is fluidly coupled to the air chamber through the air holes of the outer body and the internal receiving chamber. The decompression valve device includes a valve base received within the internal receiving chamber, the valve base defining an internal chamber extending between a first end and a second end. The first end of the valve base includes a decompression opening in fluid communication with the air outlet, and the second end of the valve base is fluidly coupled to the air chamber through the air holes of the outer body and the internal receiving chamber. A valve body and a seal are supported within the internal chamber of the valve base. The valve body is supported for movement relative to the seal between a sealed state and an open state. Air pressure inside the air chamber less than or equal to a decompression value causes the valve body and the seal to be in the sealed state where air flow is blocked through the decompression opening. Air pressure inside the air chamber greater than a decompression value causes the valve body and seal to be in the open state where air flow is permitted through the decompression opening.

According to yet another embodiment of the present disclosure, an air valve assembly includes an outer body defining an internal receiving chamber and having a plurality of air holes fluidly coupling the internal receiving chamber and an air chamber of an inflatable product. An air outlet is supported by the body and is configured to provide selective communication between the air chamber and atmosphere. An air valve device is supported by the outer body and is fluidly coupled to the air chamber through the air holes of the outer body and the internal receiving chamber. The air valve device includes a seal movable between a sealed state and an open state. The seal cooperates with the outer body to block air flow in the sealed state, and the seal is in spaced relation to the outer body to define a passageway between the seal and the outer body in the open state. A decompression valve device is supported by the outer body and is fluidly coupled to the air chamber through the air holes of the outer body and the internal receiving chamber. A decompression valve device is supported by the outer body and is fluidly coupled to the air chamber through the air holes of the outer body and the internal receiving chamber. The decompression valve device includes a valve base received within the internal receiving chamber, the valve base defining an internal chamber extending between a first end and a second end, the first end including an upper wall having a decompression opening in fluid communication with the air outlet, and the second end fluidly coupled to the air chamber through the air holes of the outer body and the internal receiving chamber. A valve body is supported within the internal chamber of the valve base, the valve body including an upper wall having a valve body opening in fluid communication with the decompression opening. A valve spool and a valve body seal are operably coupled to the valve body, the valve body seal supported by the valve spool and configured to selectively block the valve body opening. A valve body spring is received within the internal chamber of the valve base and biases the valve body away from the upper wall of the valve base and toward the valve body seal. The valve body is supported for movement relative to the valve body seal between a sealed state and an open state. A valve spool spring biases the seal toward the valve body opening. A limit portion is operably coupled with the seal, wherein air pressure inside the air chamber less than or equal to a decompression value causes the valve body and the valve body seal to be in the sealed state where air flow is blocked through the valve body opening and the decompression opening. Air pressure inside the air chamber greater than a decompression value causes the valve body seal to abut the limit portion and move the valve body relative to the valve body seal from the sealed state to the open state where air flow is permitted through the valve body opening and the decompression opening.

DETAILED DESCRIPTION OF THE DRAWINGS

An illustrative decompression air valve assembly 100 of the present disclosure is shown in FIGS. 1-5. With reference to FIG. 5, air valve assembly 100 is configured for use with an inflatable product 4, such as a mattress, chair, pool, spa, float, or another suitable inflatable product. Inflatable product 4 may include an external or outer wall 41 that defines one or more air chambers 42. Valve assembly 100 includes a first or fill/deflation air valve component or device 1 that serves as an air inlet for inflation/deflation of inflatable product 4, and a second or decompression valve component or device 2 that serves as an air outlet for deflation or decompression of inflatable product 4 by venting to atmosphere 102.

With further reference to FIGS. 1-4, the air valve component 1 of the valve assembly 100 illustratively includes an outer body defined by an upper body 11 and a lower body 12. In the illustrated embodiment of FIG. 2, upper body 11 is threadably coupled to lower body 12. Upper body 11 includes an air valve 111. As shown in FIG. 3, upper body 11 also includes one or more internal ribs 114 that define an internal passageway 112, and a groove 113 surrounding internal passageway 112. As shown in FIG. 2, lower body 12 defines an internal accommodating or receiving chamber 121 and one or more air holes 122 in the side wall 123 and/or the bottom wall 124 of lower body 12 that allow air to pass through lower body 12 between internal receiving chamber 121 of lower body 12 and air chamber 42 of inflatable product 4 (FIG. 5).

As shown in FIG. 2, the second or decompression valve component 2 includes a decompression passage 210 selectively connecting the air chamber 42 to atmosphere 102. More particularly, the decompression valve component 2 is received in the internal chamber 121 of lower body 12 and is configured to selectively close the decompression passage 210. The second valve component 2 includes a sealing portion having a valve base 21, a valve body 22, and a valve spool component 23. The valve base 21 includes an internal chamber 211 that is aligned with and fluidly communicates with internal receiving chamber 121 and air holes 122 of lower body 12 and hence with air chamber 42.

As shown in FIG. 3, a valve rod 212 extends upward from valve base 21 through internal passageway 112 of upper body 11 and away from internal chamber 211. A valve spring 213 is disposed around valve rod 212. A lower end of valve spring 213 is retained by being received in groove 113 of upper body 11, and an upper end of valve spring 213 is retained by being received beneath a screw 214 and a nut 215. Under the force of valve spring 213, nut 215 of the second valve component 2 is biased upward relative to upper body 11. A seal 216 (e.g., an O-ring) may be provided around valve rod 212 between the upper end of valve base 21 and the lower end of upper body 11.

The first air valve component 1 may have a normally sealed state or position and an open state or portion. In the sealed state, valve spring 213 lifts valve base 21 and seal 216 upward and into sealed engagement with upper body 11. In this sealed state, seal 216 blocks communication between air valve 111 in upper body 11 and internal chamber 121 in lower body 12. In the open state, a user manually presses nut 215 downward to compress valve spring 213. Valve base 21 and seal 216 also move downward and away from upper body 11 to define a passageway between the valve base 21 and the upper body 11, which places air valve 111 in upper body 11 in fluid communication with internal chamber 121 in lower body 12. The second valve component 2 may be placed in the open state when inflating or deflating the air chamber 42 of the inflatable product 4 (FIG. 5).

Valve body 22 and valve spool component 23 are received in internal chamber 211 of valve base 21, as shown in FIG. 4. With reference to FIGS. 1 and 2, the upper end of internal chamber 211 is in fluid communication with one or more one-way decompression holes 217 supported by a lateral upper wall 220 of the valve base 21, and the lower end of internal chamber 211 is in fluid communication with the internal receiving chamber 121 and the air holes 122 of the lower body 12. Valve body 22 defines a valve body opening or hole 221 in its upper end. Valve spool component 23 includes a valve spool 231 and a sealing element or seal 232 positioned between an upper surface of valve spool 231 and a lower surface of valve body 22 near hole 221. A limit portion or projection, such as a post or thimble 218, extends downwardly from valve base 21 into internal chamber 211, through hole 221, and toward valve spool component 23. A first, or valve body spring 219 is positioned in internal chamber 211 of valve base 21. An upper end of spring 219 abuts the upper wall 220 of the valve base 21, and a lower end of spring 219 abuts the valve body 22.

A second, or valve spool spring 233 is illustratively positioned between valve body 22 and valve spool component 23. A flexible bellows 234 is received within the internal chamber 211 of the valve base 21 and includes a first end coupled to the valve body 22 through a retainer 236. An end cap 238 is threadably coupled to the second end of the valve base 21. A second end of the bellows 234 is coupled to the end cap 238, such that the bellows 234 extends and retracts in response to longitudinal movement of the valve body 22 within the internal chamber 211 of the valve base 21.

With reference to FIGS. 1, 4 and 5, the second valve component 2 may have a normally sealed state or position and an open state or position. In the sealed state of the second valve component 2, the pressure inside the air chamber 42 of the inflatable product 4 (FIG. 5) forces valve spool 231 and seal 232 upward and into sealed engagement with valve body 22. In this state, seal 232 closes hole 221 to block airflow through internal chamber 211 of valve base 21.

When air pressure in the air chamber 42 of the inflatable product 4 is lower than a decompression value, the valve body 22 resets under the action of the valve body spring 219. More particularly, the valve body spring 219 pushes downwardly against the valve spool spring 233 and drives the sealing element 232 to again close the hole 221. Characteristics of the valve body spring (e.g., spring constant (elasticity), length, etc.) may be set based upon the desired decompression value of air pressure. As such, the second valve component 2 automatically seals after decompression. When the air pressure of the air chamber 42 is lower than the decompression value, the elastic force of the valve body spring 219 causes the valve body 22 and the valve spool component 23 to move away from the thimble 218.

In the open state of the second valve component 2, the pressure in the air chamber 42 of the inflatable product 4 increases, and valve body 22 and the valve spool component 23 move towards the thimble 18 under the increased air pressure. When the thimble 218 abuts against the sealing element 232, the valve spool spring 233 is compressed. When the air pressure of the air chamber 42 is less than or equal to the decompression value, the thimble 218 abuts against the sealing element 232, thereby sealing the hole 221. When the air pressure of the air chamber is greater than the decompression value, the valve body 22 keeps moving, the valve spool component 23 stops moving by the limiting of the thimble 218, so that the valve spool component 23 separates from the valve body 22, the decompression hole 217 is connected to the air chamber 42 to exhaust air out from the air chamber 42 of the inflatable product 4 (i.e., automatically decompressing).

During automatic decompression, the valve spool component 23 is continuously abutted against, and has its upward movement limited by, the thimble 218. As such, the valve spool component 23 does not move up and down under flowing air, so that the service life of the valve spool component 23 may be effectively lengthened.

Therefore, when the air pressure of the air chamber 42 is lower than the decompression value, the valve spool component 23 is forced upwardly by the valve spool spring 233 and the air pressure of the air chamber 42, such that the sealing element 232 abuts against the valve body 22 and seals the hole 221. When the air pressure of the air chamber 42 is greater than the decompression value, due to the relatively weak elastic force of the valve spool spring 233, the sealing element 232 is configured to open quickly for decompression (i.e., has a quick response time). Furthermore, when the air pressure of the air chamber 42 reduces to below the decompression value, as the elastic force of the valve spool spring 233 is far lighter than the elastic force of the valve body spring 219, the valve spool spring 233 resets quickly under the action of the valve body spring 219, thus stopping decompressing quickly and reducing the likelihood of over decompressing air in the air chamber 42.

In the illustrative embodiment shown in FIGS. 1 and 2, an air valve cover 3 is inserted in the air valve 111. The air valve cover 3 includes an air outlet 31, which is connected to the decompression hole 217 by the internal passageway 112 of the upper body 11. Air is configured to selectively flow out of the decompression hole 217 and then the air outlet 31 by operation of the decompression valve component 2. More particularly, the second or decompression valve component 2 includes decompression passage 210 selectively connecting the air chamber 42 to atmosphere 102. The decompression passage 210 illustratively extends from the air chamber 42, through the internal chamber 121 of the lower body 12, the internal chamber 211 of the valve base 21, the decompression holes 217, and through the internal passageway 112 of the upper body 11 to the air outlet 31.

In the illustrative embodiment shown in FIG. 5, the outer wall 41 of the air chamber 42 is illustratively positioned in an abutting relationship between the upper body 11 and the lower body 12. More particularly, the outer wall 41 is illustratively sealed with the upper body 11 and the lower body 12 by the abutting force between the upper body 11 and the lower body 12.

It should be noted that, the limit portion (e.g., the thimble 218) of the illustrative embodiment of FIGS. 1-5 is shown disposed at the top end of the internal chamber 211. More particularly, the thimble 218 may extend downwardly from the upper wall 220 of the valve body 22 (FIG. 4). As needed, the thimble 218 can be disposed at other positions for releasing the sealing relationship of the valve spool component 23 and the valve body 22 when the air pressure increases. With reference to the illustrative embodiment of FIG. 6, the thimble 218 may extend upwardly from the valve spool component 23.

Referring now to the illustrative embodiment of FIG. 7, the second or decompression valve component 2 comprises valve base 21, valve body 22 and valve spool component 23. Valve body 22 is received within first chamber 211 a of valve base 21, while the valve spool component 23 is received within second chamber 211 b. The first chamber 211 a and second chamber 211 b are fluidly connected with each other, via a connecting passageway 222, and with the internal chamber 121 (see FIG. 2). More particularly, one end of the second chamber 211 b is fluidly connected to the air chamber 42 via the internal chamber 121, and the valve spool component 23 is disposed in the second chamber 211 b. The valve spool component 23 abuts against and closes the connecting portion between the first chamber 211 a and the second chamber 211 b by the air pressure in the air chamber 42.

The valve body 22 is disposed in the first chamber 211 a, one end of the first chamber 211 a is connected to the internal receiving chamber 121, so that the valve body 22 moves in the first chamber 211 a by the influence of the air pressure in the air chamber 42. The other end of the first chamber 211 a is disposed with decompression holes 217 connected to the air valve 111. The decompression holes 217 and the air chamber 42 are separated by the valve body 22. The valve body 22 is further disposed with a limit portion 218, such as a post or thimble. More particularly, the limit portion 218 may comprise a thimble disposed at the top end of the internal wall of the valve body 22 along the length direction of the valve body 22.

When air pressure in the air chamber 42 increases, the valve body 22 moves toward the valve spool component 23 by the air pressure. When air pressure in the air chamber 42 reaches the decompression value, the limit portion 218 abuts against the valve spool component 23. When the air pressure in the air chamber 42 is higher than the decompression value, the valve spool component 23 moves away from the connecting passageway 222 of the first chamber 211 a and the second chamber 211 b under the limit action of the limit portion 218. The decompression hole 217 connects the second chamber 211 b and the air chamber 42 to exhaust in the air chamber 42 out from the valve assembly 100.

As shown in the illustrative embodiment of FIG. 8, external wall 41 of the air chamber 42 includes a lower surface sealed to the upper surface of the lower body 12 by high-circle welding or gluing. The external wall 41 of the air chamber 42 includes an upper surface illustratively sealed by the abutting force between the air valve cover 3 and the lower body 12. In other illustrative embodiments, the air valve cover 3 does not apply an abutting force to lower body 12 and, in fact, has holes to allow air to escape when the over pressure condition occurs. The remaining components of this illustrative embodiment are substantially similar to those of the illustrative embodiment of FIGS. 1-5.

While this invention has been described as having exemplary designs, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles.
